Oh my god there's still people active around here

Well, just like tudgirl, I have a Note7 without a battery (I threw mine away just worried it'd catch on fire), and so I have no OG battery controller on hand. There's a listing on eBay for an original Note7 battery, but it dates to 2016, so that's probably the bad ones. I also have no welding tools anywhere near me

My best guest has been to search for a Galaxy battery with the same layout/connector as the Note7. For example, the Note5 or S7. I have a Note5 (not working) and an S6 edge, they served to help me see the physical differences on the battery connectors and I think maybe the S7 would work here, but I don't have a welding tool to do any of that stuff
Is there any advise? anyone who sells broken FE's or something of the likes?
